Aluminium hulls

Has anybody tried or got an ally hulled rib? 3D Tender have some. Any good?

I have a 2.9 Scorpion Stinger. amazingly well built and extremely solid. These are an Australian dinghy. I have a 9.9 on it and it flies.

I also have a 5.6 Dockitjet that is very light, about 140kg with a fiberglass console. Aluminium is very easy to make changes by welding on bits you want.

They seem to make sense to me. But my main concern is the rubber to ally adhesion. As there is no resin/resin or epoxy interaction.........is this an issue or is there a different interface involved?

Your looking at buying something made of alloy... Land Rovers are made of alloy.....

Now now Chewy.........

Just so you know.......if you want to corrode a metal, here's the way to do it.
Put an untreated aluminium sheet next to a half sniffed at steel box section ( raw inside ), and finish off the circuit ( assuming it's a -/+ve earth system ) with an untreated iron fastener joining the two metals. Not just placed between them but threaded and screwed as a joint in order to properly open up the surfaces of the relevant metals to promote their conductivity. And then add water ( salty for us) and electricity.
I'm surprised Defenders don't charge their own batteries overnight........they should at least contribute to the Grid.

I have one. Pictures in my gallery. http://www.rib.net/forum/members/4333-albums170.html

Glueing the tube on is not really any different than glueing hypalon to GRP. I think they even use the same sikaflex.

How many rotted transoms and anchor lockers have you seen on here? With an ali hull all that is moot.

mister p · 05 January 2012, 22:29

There you go.....that's what I thought. One solid tub. Now I'm thinking.........Polaris eh?
Who else does ally hulls?

Stabicraft and Safeboats both make foam collared ali boats, they are basically RIB-like.
Terminator makes ali RIBs

Stabicraft and Terminator are both in New Zealand. Safeboats are here in Washington State.

Non-RIB Aluminum fishing boats are highly desired here. Its a proven hull material.

Ribeye do some alli tenders that seem to have been well received by the boating press.

I have a POLARKRAFT and she's sharp as hell but with that flighty. Not for open water.

Foam collars are not for me, though thankyou.

I'll investigate Terminators.

Cheers for your response captn

Saw a few different makes at the Southampton Show, some with hypalon toobs.

The 3D tender boats looked pretty good and they had a load of different variants in their range. PVC toobs though.

"flugga".........remind me, are they ally tubed? Don't want that, just maybe ally hull.

Polypipes - ambient pressure. Indestructable.

Specmar Is another, they have a drawing on their website. Ali ribs are damned expensive, for a circa 9m diesel you're looking at £85-100k starting price

Also Alimal ribs are uk built, much more affordable I think but I've seen one at Seawork, pretty agricultural looking, not finished to the highest standard.

Zodiac and Willard will both do aluminum....as does Northwest Marine up in Washington state.
